Why is chromium oxide the most important and valuable use as pigment?
What is chromium oxide?
Chromium oxide green is a hexagonal crystal system or amorphous dark green powder with a metallic luster. It usually has two color phases: light olive green and dark olive green, with metallic color. Relative density is 5.21, melting point: is 2266 ℃, and boiling point is 4000 ℃. It has an excellent heat resistance and can withstand 1000 ℃ without discoloration, acid resistance, and alkali resistance. The product has high purity, small particle size, uniform distribution, and extremely hard crystals. Very stable, There is no change even when hydrogen is introduced under red heat. It is soluble in heated potassium bromate solution, slightly soluble in acids and alkalis, and almost insoluble in water, ethanol, and acetone.
Structure of chromium oxide
Chromium oxide is an octahedral structure. In this octahedron, six 0-0 bonds are 0.496mm long, the other six 0-0 bonds are 0.536mm long, and six Cr-0 bond phases are 0.365 mm long. Therefore, chromium oxide crystal is connected by deformed [GO6] 9 octahedrons through coplanar, coplanar, and coplanar and other complex ways. The coordination of CP in [CfOg] 9 is only Ca. Symmetry and its coordination symmetry will affect its chromogenic properties.
Use of chromium oxide
The most important and valuable use of Cn2O3 is as a pigment. The price of chromium oxide in the international market depends on the preparation method and use, and the pigment grade is the most expensive. The chrome green products used as pigments and coatings have many requirements regarding chroma, color difference, color quality, absorption, dispersibility, etc. In addition to being used solely as pigments, mixed-phase pigments containing C2O3 have also been reported. For example, Cn2O3 is the basic component of various pigments with different crystal forms; the colors of these pigments are all over visible light. In the spinel (Zn. Mg) (Fe, Cr) 2O4 system lattice, with the change of cations, the hue of earth yellow to dark brown can be obtained ".
Price of chromium oxide
Chromium oxide particle size and purity will affect the product's price, and the purchase volume can also affect the cost of chromium oxide. A large amount of large amount will be lower. The price of chromium oxide can be found on our company's official website.
